Methane abatement and geoengineering have a short-lived effect on temperature compared with carbon abatement. Different optimal tax paths for these actions arise in a cost-benefit framework with an unknown temperature threshold where severe and irreversible climate impacts, called a tipping...

This paper describes an integrated assessment model with an unknown temperature threshold where severe and irreversible climate impacts, called a tipping point, occurs. The possibility of tipping leads to the following linked outcomes: a prolonged period of peak temperature; a rebound in...

Auf nationaler und auf europäischer Ebene sind die zuvor bestehenden Klimaziele deutlich verschärft worden. Die neuen Vorgaben, mit denen in Deutschland 2045 und in der EU27 bis 2050 Treibhausgasneutralität erreicht werden soll, werden ebenso dargestellt wie die Instrumente, mit denen die...

This paper identifies a previously unnoticed problem important for the efficient reduction of GHG emissions: the pricing of off-peak electricity. There may be many opportunities to reduce emissions by substituting relatively clean and inexpensive off-peak electricity in place of a more...

The introduction of a price on carbon dioxide will have important effects on the U.S. economy, and especially important effects on the electricity sector, which currently accounts for about 40 percent of carbon dioxide emissions. This paper examines alternative approaches to the distribution of...

There has been intense focus on the issue of how emissions allowances might be allocated under a potential federal cap-and-trade program. What fraction of the allowances should be auctioned out, as opposed to given out free? How much free allocation would be sufficient to preserve profits in...

This paper considers whether the California Air Resources Board, in implementing regulations to achieve the greenhouse gas reduction goals of the AB32 legislation, should include motor vehicle fuels as part of a cap-and-trade program. Its conclusion is that it is of importance to do so. While...

I propose a new climate policy, called greenhouse gas (GHG) property, that makes atmospheric GHG stocks the unit of regulation. The initial extractor or importer of a fossil fuel would own tradable carbon property that would become carbon dioxide (CO2) property upon combustion. This CO2 property...

This paper highlights the importance of carbon dioxide removal (CDR) technologies for climate policy. We first describe their role in iconic transformation pathways and discuss removal costs and storage duration of different technologies. Based on economic principles, we characterize optimal...

Domestic carbon pricing policies may impose adverse competitiveness risks on energy-intensive firms and industries competing with foreign firms that may bear a lower or zero price on carbon. The risks of competitiveness effects include adverse economic outcomes — reduced production, lower...
